1、From the LOADER prompt, boot the recovery image from the USB flash drive:boot_recovery
The image is downloaded from the USB flash drive.

Execute this command after inserting the USB.

boot_recovery 97P23_q_nodar_image.tgz

The machine's reaction is as follows

Downloading 97P23_q_nodar_image.tgz .. Extracting archive r_image.tgz ..

2、When prompted, either enter the name of the image or accept the default image displayed inside the brackets on your screen.

3、Restore the var file system:

A network connection

1. Press y when prompted to restore the backup configuration.

2. Set the healthy node to advanced privilege level:set -privilege advanced

3. Run the restore backup command:system node restore-backup -node local -target-address impaired_node_IP_address

4. Return the node to admin level:set -privilege admin

5. Press y when prompted to use the restored configuration.

6. Press y when prompted to reboot the node.

No network connection

1. Press n when prompted to restore the backup configuration.

2. Reboot the system when prompted by the system.

3. Select the Update flash from backup config (sync flash) option from the displayed menu.

   If you are prompted to continue with the update, press y.

4、Verify that the environmental variables are set as expected.

1. 1. Take the node to the LOADER prompt.

   2. Check the environment variable settings with the printenv command.

   3. If an environment variable is not set as expected, modify it with the setenv environment_variable_name changed_value command.

   4. Save your changes using the saveenv command.

   5. Reboot the nodehe               

5、The next step depends on your system configuration

If netapp doesn't load...

Steps​

1. Look for a description of the problem on the console.

   You must follow any instructions provided on the console.

2. Check all cables and connections, making sure they are secure.

3. Ensure that power is supplied and is reaching your system from the power source.

4. Make sure that the power supplies on your controller and disk shelves are working:

   If the LEDs on a power supply are...​	Then...​
   Illuminated	Proceed to the next step.
   Not illuminated	Remove the power supply and reinstall it, making sure that it connects with the backplane.

5. Verify disk shelf compatibility with your version of Data ONTAP and ensure that the disk shelf IDs are unique.

   For more information, see the Hardware Universe.

6. If your system has SAS shelves, go to step 7; otherwise ensure that the Fibre Channel disk shelf speed is correct.

7. Check disk ownership to ensure that the disks are assigned to the system:

   1. Boot into maintenance mode and select option 5.

      If you cannot boot into the 1-5 menu, you probably have an issue with the boot image or the CF card. Contact technical support.

   2. Verify that disks are assigned to the system by entering disk show.

   3. Validate that storage is attached to the system, and verify any changes you made, by entering disk show -v.

8. Turn off your controller and disk shelves, and then turn on the disk shelves.

   For information about LED responses, check the quick reference card that came with the disk shelf or the hardware guide for your disk shelf.

9. Use the onboard diagnostics to check that Fibre Channel disks in the storage system are operating properly:

   1. Turn on your system and press Ctrl-C.

      Enter boot_diags at the LOADER> prompt.

   2. Enter fcal in the Diagnostic Monitor program that starts at boot.

   3. Enter 73 at the prompt to show all disk drives.

   4. Exit the Diagnostic Monitor by entering 99 at the prompt, as needed.

   5. Enter the exit command to return to LOADER.

   6. Start Data ONTAP by entering autoboot at the prompt.

10. Use the onboard diagnostics to check that SAS disks in the storage system are operating properly:

    1. Enter boot_diags at the LOADER> prompt.

    2. Enter mb in the Diagnostic Monitor program.

    3. Enter 6 to select the SAS test menu.

    4. Enter 42 to scan and show disks on the selected SAS.

       This displays the number of SAS disks.

    5. Enter 72 to show the attached SAS devices.

    6. Exit the Diagnostic Monitor by entering 99 at the prompt, as needed.

    7. Enter the exit command to return to LOADER.

    8. Start Data ONTAP by entering autoboot at the prompt.

11. Try booting your system again:

    If your system...​	Then...​
    Boots successfully	Proceed to set up the software.
    Does not boot successfully	Contact technical support. The system might not have the boot image downloaded on the boot device.

    Depending on your storage controller model, see the Diagnostics Guide or System-Level Diagnostics Guide for more information about running diagnostics.
